The most common symptom of rectal cancer is blood in the stool, often there is blood on the stool paper after the stool, this time pay special attention to go to the hospital for examination, because many people have the problem of hemorrhoids, the symptoms of hemorrhoids are very similar to this, so at this time if you arrive at the hospital, the doctor to do an anal examination or a simple anoscopy, is very valuable for the diagnosis of rectal cancer. Similar hemorrhoids with rectal cancer is not uncommon in clinical practice. According to the data, the incidence of hemorrhoids in the general population is as high as 45% to 50%, and the incidence of colorectal cancer is 2.5%, of which rectal cancer patients account for 40% to 50% of colorectal cancer. It is entirely possible for hemorrhoids and rectal cancer to occur in the same patient. The clinical manifestations of hemorrhoids are mainly fresh blood stools and anal discomfort, and these signs are very much the same as those of rectal cancer. The similarity of symptoms, coupled with the fact that most patients always believe that they are unlikely to have cancer, so they often ignore the condition. Therefore, those who have blood in their stool should be extra vigilant. The most common symptom of rectal cancer is blood in the stool, often there is blood on the stool paper after the stool, this time pay special attention to go to the hospital for examination, because many people have hemorrhoids, the symptoms of hemorrhoids are very similar to this, so at this time, if you go to the hospital, the doctor to do an anal examination or a simple anoscopy, is very valuable for the diagnosis of rectal cancer. If rectal cancer is detected early, the surgical resection rate can reach 100% and the 5-year survival rate can be over 80%, so early prevention of rectal cancer is the key. However, in our life, many patients often do not pay attention to the symptom of blood in stool, which may cause tragedy due to delaying the disease. In the last six months or so, 65-year-old Uncle Chen often blood in the stool, Uncle Chen has been thinking that they are hemorrhoids again, so they bought some drugs to treat hemorrhoids, but after oral and external “self-treatment”, “hemorrhoids” has not improved. The actual fact is that you can find a lot of people who are not able to get the best out of the company. The most important thing is that you can’t afford to go to the hospital and find out that the root of the problem is not hemorrhoids, but rectal cancer, and it is already in the middle. “People who misjudge themselves like Uncle Chen account for the majority of rectal cancer patients, and the ratio reaches 50% to 80%.” Experts from Fuzhou Anorectal Hospital pointed out that blood in the stool is not necessarily hemorrhoids, but may be rectal cancer. In the recent week, the hospital has detected four patients with rectal cancer, while more than 150 people were detected with rectal cancer in 2008, and the age of onset of rectal cancer has a tendency to decrease. The early diagnosis rate of rectal cancer in young people is very low, and the malignant degree is high, and once diagnosed, it is basically late. Not long ago, a 28-year-old young man came to the hospital for examination and was in the advanced stage of rectal cancer, which could not be treated with open surgery. According to experts, “rectal cancer is most likely to be misdiagnosed as ‘hemorrhoids’, but in fact there is a clear difference between the two, which can be identified by careful observation. Hemorrhoids manifest as dripping blood and bleeding after stool, while rectal tumor bleeding is blood on the surface of stool; secondly, the amount of bleeding between the two is also very different; hemorrhoids may bleed almost every time when it is difficult to defecate, while rectal cancer bleeding is not much and not necessarily every time.” It is understood that rectal cancer develops slowly and it takes a year for cancer cells to invade one circle of the intestinal canal, and its early symptoms are often hidden. It should be reminded that the change of patients’ bowel habits may also be an early signal of rectal cancer. Under normal circumstances, everyone has a certain regularity of bowel movement, either once a day or once every other day. After rectal cancer, the regular bowel habits change: constipation, once every three or four days; diarrhea, four or five times a day or even more; or alternating constipation and diarrhea; or the feeling of incomplete bowel movement and poor defecation after defecation. This kind of alternating constipation and diarrhea is a very important alarm signal from rectal cancer. According to experts, once the symptoms of blood in stool appear, you should have a colonoscopy in time to find out the real cause to avoid delaying the disease. Special attention should be paid to five high-risk groups: people with family history of colorectal cancer, people with polyps in the colon, people with recurrent inflammatory bowel disease, people who like high-fat diet, and people who have had schistosomiasis. If you have bleeding stools, do not easily think that it is just “hemorrhoids”, but should go to the hospital for further examination and take the initiative to prompt the physician to make the correct diagnosis.
